Figure 96: Configuring echo cancellation
Description
Enables/disables AGC. Automatic Gain Control (AGC) smooths audio
signals through normalization, by lowering sounds which are too strong and
strengthening sounds which are too weak.
Typically, you enable AGC for optimal audio. However, you may want to
disable it if your microphone is strengthening the sound of background
noise, mistaking it for your voice.
Enables/disables reduction of background noise in a conference room (like
coughing, paper rustling, or the hum of an air conditioning system).
Typically, you enable Noise reduction for optimal audio. However, you
may want to disable it some voices are filtered out as background noise,
which causes breaks in the audio.
An HDMI monitor might cause a delay in the audio, causing an echo.
Set this field to Yes to improve its echo cancellation performance
automatically. We recommend this setting when you connect a new monitor
to the XT Series.
If you set this field to No, you can generate the audio delay manually and
train the echo cancellation to use the resulting audio for better
performance. For details, see
page 183.
Select Yes to use the estimated audio delay.
Typically, you enable Audio delay for optimal audio. However, you may
want to disable it if your room has a strong echo that creates a
reverberating effect, which may produce false results when estimating the
audio delay.
